Description

Ethernet performance measurement method, apparatus and system

Technical field

The present invention relates to internet arenas, and in particular to a kind of ethernet performance measurement method, device for measuring properties and is System.

Background technology

International Telecommunication Union organizes（International telecommunications union, abbreviation ITU）It formulates The operation of ether layer, management and maintenance（Operation, administration, maintenance, abbreviation OAM）Agreement carries Fault management is supplied（Fault management, abbreviation FM）And performance monitoring（Performance monitoring, referred to as PM）Two kinds of functions；The packet losses of Ethernet messages, time delay, the method for shake are measured there is defined a series of so that operator can be with The service level agreement of network is obtained in real time（Service level agreement, SLA）, network performance problems are found in time

Although the OAM agreements that ITU-T is defined solve two layers of Ethernet, the end to end performance in point-to-point networking measures Problem can realize Maintenance Entity（Maintenance entity group, abbreviated as MEG）Interior Maintenance Entity endpoint （Maintenance entity point, abbreviation MEP）The performance measurement of MEP to MEP, but work as carrier network or enterprise network When disposing OAM agreements in network and carry out ethernet performance measurement, and measuring network performance problems, it is also necessary to do further failure Positioning.For two layers of Ethernet, existing OAM protocol definitions are measured using Ethernet packet loss（Ethernet loss measurement,ETH-LM）, ethernet delay measure（Ethernet delay measurement, ETH-DM）Equal messages into Packet loss, time delay and the test method of shake of row end to end network, can be by dividing the maintenance domain of different range, and each Safeguard that domain is respectively started independent performance test task and carrys out positioning failure.

But the prior art have the shortcomings that it is as follows：

First, need to configure it is multiple safeguard domain, start multiple performance test tasks, and each measuring node be both needed to be related to it is more The configuration of a test parameter, configuration work amount is very big, and it is long to expend the time.

Second, multiple domain measurement can not ensure to carry out performance measurement based on identical time reference.It is safeguarded in domain due to each Performance test task it is mutual indepedent, same Business Stream is delimited using different packet loss measured messages, uses difference Latency measurement message make latency measurement, the time reference of test is different.Therefore multiple performances for safeguarding domain can not directly be used Test data makees the comparative analysis with the period, influences the accuracy of fault location.

Third, multiple domain measurement consuming system resource is more, influences system test specification.When fault location, multiple maintenances are needed Performance test tasks in parallel in domain, occupancy device resource is more, is each test assignment as the measurement of packet loss needs MEP nodes It individually distributes 2 counters and using 2 accesses control lists (Access Control List, ACL) rules, cannot only match The performance measurement that 1 test assignment just completes each section of network is set, the maximum performance test case number of equipment support is affected.

That there are efficiency is low, complexity is high when in conclusion the prior art carrying out end to end performance monitoring to Ethernet asks Topic.
